ERP. The software that gets orders, stock and invoices talking to each other.

An ERP (enterprise resource planning) is the management software that links a company's functions on the same database: sales, purchasing, stock, production, accounting, staff. Every piece of information is written once, and every department sees it.

This entry is part of the glossary of AI and automation, where every term has a short definition. Here the definition widens: which modules an ERP contains, how widespread it is among Italian enterprises, what sets it apart from simple management software and from a CRM, and when it is needed.

What is an ERP

For Eurostat, the statistical office of the European Union, the defining feature of ERP is that it is built in modules, «delivered in ‘modules’ that typically integrate processes relevant to planning, purchases, marketing, sales, customer relationship, finance and human resources». What holds them together is a shared database.

Without an ERP every department has its own program or spreadsheet, and data moves from one to the other by hand. The order arrives by email, someone retypes it into the warehouse program, someone else copies it into the invoice. Every step costs time and opens the door to an error. With an ERP the data is created once, at the point where it enters the company.

The modules of an ERP

The most common modules are six, and each one reads the data of the others. No small business switches them all on the first day: you start with those where work repeats the most and add the rest once the first piece works.

Module	What it manages	What happens without retyping
Salesorders and price lists	Quotes, customer orders, price lists, payment terms.	The confirmed order reserves the goods in stock.
Purchasingsuppliers	Purchase orders, goods received, matching against supplier invoices.	Goods received update stock levels and wait for the right invoice.
Stocklevels and batches	Available quantities, batches, expiry dates, movements.	Availability is the real one, with no end-of-day counts.
Productionbills of materials and stages	Recipes or bills of materials, work stages, times, consumption.	The batch produced deducts the raw materials used.
Accountinginvoices and due dates	Sales and purchase invoices, bookkeeping, collections, payments, financial statements.	The fulfilled order becomes an electronic invoice with the data already right.
Staffhours and costs	Attendance, shifts, hourly cost.	Labour cost goes into the margin of every job.

You usually start with accounting and sales, where the need is already written into law. Since 1 January 2019, as the Italian Revenue Agency reports, invoices between parties resident or established in Italy are electronic only: every business invoicing in Italy therefore already has a tool to issue them, and from there an ERP is built by adding pieces.

How widespread it is among Italian enterprises

In 2025, 49.5% of Italian enterprises with at least 10 employees use an ERP, according to Eurostat: it is the most widespread business software in the survey, ahead of CRM (21.7%) and business intelligence (16.0%). The EU average is 46.5%. Across sectors in Europe, the lowest share is in accommodation and food services, at 26.7%.

Enterprise size	Italy	European Union
Small10 to 49 employees	46.0%	41.1%
Medium50 to 249 employees	71.9%	69.9%
Large250 employees or more	85.9%	88.7%
All10 employees or more	49.5%	46.5%

The survey counts enterprises that have an ERP to share information between departments. How many modules are actually switched on, and how much data still moves by hand from one department to another, no statistic says: you only see it by looking at a week of work.

ERP, management software and CRM

In Italy «gestionale» is the everyday word, ERP the technical one. A management program that only does invoices, bookkeeping and stock covers some modules; it becomes an ERP when it links sales, purchasing, stock and accounting on the same database. The CRM sits upstream, on relationships with customers before they turn into orders.

Question	ERP	CRM
Where it looksthe scope	Inside the company: orders, stock, invoices, accounting.	Outside: contacts, requests, deals, support.
Where it startsthe first data	From the order.	From the first contact, often weeks before the order.
Who uses itevery day	Administration, warehouse, production.	Sales, support, the owner.
What it measuresthe numbers that come out	Margins, stock levels, collections, delivery times.	Requests, response times, open and closed deals.

When you need one, and what to ask

An ERP is needed when the same data is written by hand in two places. The signal is retyping: the order received by email and retyped into the management software, the delivery note keyed again into the invoice, the stock level nobody knows for sure. In the Barchard and Pace study about 1% of data transcribed by hand contains an error, and checking by eye does not reduce it.

Does it connect to what you have? Ask which programs talk to the ERP without retyping: email, the website, the CRM, the accountant.

How do you get out? An ERP is an expensive choice to redo. Ask what format the data exports in and whether the export includes the history.

Who adapts it to your work? Modules and flows have to be configured around how you work. Ask who does it, how long it takes and at what price, before signing.

How Itria works with an ERP

Itria works with the management software you already have, and it is the fourth of the principles written in Ethics: «The tools you already have aren't scrapped». We build the steps around the management software, where data is retyped today: documents in PDF, orders arriving by email, the numbers the owner wants to read in the morning.

The piece closest to the ERP is automatic document entry: orders, delivery notes and invoices from foreign suppliers read and extracted into structured data, with OCR where needed. On a test bench on 4 September 2026, with 30 documents, 234 of 237 extracted fields were correct, 98.7%.
